Monster Hunter 3! - This Nub needs help please! :)

Hi there, I softmodded my first Wii about a month back and I've been playing games just fine and messing around with some stuff. I'm a big fan of the Monster Hunter series and I've downloaded the patched version of MH 3/Tri as of August and used IMGburn to put it onto disc. Can someone please talk me through how best to load this disc on my wii and what files/Wads I may need to install to get it to work? With links of course if you please, Thank you.
